GEORGE HERBERT BENTLEY, OF WESTMINSTER, LONDON, ENGLAND, ASSIGNOR 0FONE-HALE TO EDMUND GARDNER APPLEBY, OF LONDON, ENGLAND.

Application filed. March 23, 1915.

To all whom it may concern Be it known that I, GEORGE HERBERT BENTLEY, asubject of the King of Great Britain, residing at 12 The Broadway,Westminster, London, England, have invented new and useful Improvementsin Gas-Generators, of which the following is a specification.

This invention has for its object the con.- struction of a gas generatorin which caking together of the fuels and also clinker formation isprevented and a large gasification secured. To effect this purpose thefuel in the generator is kept in continual motion by not only liftingand lowering the casing of the generator relatively to the grate, butalso by simultaneously revolving the casing eccentrically around thegrate. The grate also may be revolved in the opposite direction to thecasing.

The casing, which may be circular or other desired shape, is carried bysupport and guide rings, the supporting rings being provided with camshaped pieces at intervals to give the rising and falling motion. Whenoperated by the driving gear the action is to rotate the fuel bedeccentrically around and against the fixed or rotating grate or airdistributer and also to raise and lower the casing slightly during eachrevolution. This action prevents the forma tion of blow holes andclinker in the fuel bed, the formation of any clinker or caking mass onthe walls, and by assisting the downward motion of the fuel bed theashes are more readily removed. In some cases a stationary or revolvingbar or poker is Specification of Letters Patent.

fixed eccentrically to the casing in and near the top of the fuel bed.

The invention is applicable equally to generators in which air is forcedthrough the fuel bed by pressure on the one hand or drawn through bysuction on the other.

Figure 1 is a plan (With the top removed) of a well known form of gasgenerator to which this invention has been applied. Figs. 52 and 3 aresections on the lines 2-42 and 3-3, Fig. 1, the top being shown inplace. Fig. 92 is a detached view of the rail.

a is the casing and Z) is the grate.

a a are rails fixed to the casing, these rails and the casing beingsupported'and guided by rollers c 0. V

a is a ring of teeth fixed to the casing a.

(Z is a pinion gearing with the teeth a and having fixed to it a wornwheel d driven by the worm e.

As shown at Fig. 4, the rails a are cam shaped so that a rising andfalling motion is given to the casing a as it revolves, and the pinion(Z is made long enough to allow of this. As shown at Figs. 1 and 2, thecasing a is eccentric to the grate b.

j is a revolving poker or stirrer.

What I claim is The combination of a casing, a grate, means for liftingand lowering the casing relatively to the grate, and means forsimultaneously revolving the casing eccentrically relatively to thegrate.
